离子液体基工质对的吸收制冷循环性能实验研究
Performance experiments on absorption refrigeration cycle with ionic liquid-based working pairs
摘要
Abstract
The performance test of the absorption refrigeration cycle with ionic liquid , 1-ethyl-3-methylimidazolium diethylphosphate [Emim][DEP]-based binary working pairs [Emim][DEP]+H2O and ternary working pairs LiBr+ [Emim][DEP] + H2O were conducted in order to evaluate the refrigeration effects of this new ionic liquid-based working pairs. The experiment results showed that the ionic liquid-based working pairs [Emim][DEP]+H2O was capable of refrigeration. Compared with the working pairs LiBr+H2O,[Emim][DEP]+H2O lowered the performance coefficient of refrigeration cycle due to its lower thermal conductivity and higher viscosity which led to absorbing water steam ability of [Emim][DEP]+H2O in absorber more weak under the same size of absorber. When the generation temperature and cooling water temperature were 90℃ and 30℃,respectively,the evaporation temperature was in the range of 10 to 15℃,the performance coefficient of refrigeration cycle varied from 0.16 to 0.28. In order to enhance the absorbing ability to water steam in absorber and consequently to real performance of absorption refrigeration cycle,small amount of solution LiBr+ H2O was added into the [Emim][DEP]+H2O and constituted ternary working pairs LiBr+ [Emim][DEP]+H2O, the experiment results showed that the performance coefficient of refrigeration cycle of ternary working pairs LiBr+ [Emim][DEP]+H2O was superior to that of [Emim][DEP] + H2O,and varied from 0.17 to 0.34 when the evaporation temperature was in the range of 10℃ to 15℃.关键词
